Abstract
-
- a tube head (1) comprising a shoulder (12) and a neck (11),
- a skirt (2) having a proximal end (21) which is connected to the tube head (1) and a free distal end (22), the skirt (2) forming an internal volume which is adapted to contain a product having a liquid or pasty consistency,
Description
- The present invention relates to the field of flexible tubes for storing and dispensing products having a liquid or pasty consistency, and to the methods for manufacturing such tubes.
- Flexible tubes are commonly formed by a tube head connected to a skirt, the tube head comprising a neck for removing a product contained in the tube, whereas the skirt forms the internal volume of the tube which is adapted to receive a product. The skirt is conventionally formed by a multi-layer sheet adapted to have satisfactory mechanical strength and sealing properties. The tube head is, however, usually produced by plastics injection moulding, which may prove unsatisfactory for certain applications owing to the very aggressive nature of certain products.
- To address this problem, several solutions have been proposed, including in particular an insert comprising a metal or EVOH barrier layer, which is shaped to the inner face of the shoulder of the tube head, so as to form a barrier separating the tube head itself from the product contained in the tube and thus to protect said tube head.
- However, although such an insert contributes to improving the properties of the tube head, said head has several regions having weaker properties, in particular at the edge of the insert.
- The problem addressed by the present invention is that of proposing a tube which does not have such drawbacks.
- For this purpose, the present invention proposes a flexible tube for a product having a liquid or pasty consistency, comprising:
-
- a tube head comprising a shoulder and a neck,
- a skirt having a proximal end which is connected to the tube head and a free distal end, the skirt forming an internal volume which is adapted to contain the product having a liquid or pasty consistency,
characterised in that the proximal end of said skirt comprises a plurality of flaps and a plurality of notches separating said flaps, said flaps being folded so as to cover all or part of the shoulder.
- “Cover” or “covering” means covering the tube head on the outside. In other words, the flaps are positioned on an outer face of said tube head.
- The present invention thus makes it possible to exploit the properties of the skirt in order to improve the mechanical properties of the tube head, and in particular the barrier effect thereof for protecting the product contained in the tube.
- According to a particular embodiment, said flaps are folded so as to cover at least 50% of the shoulder of the tube head.
- According to a particular embodiment, said folded flaps extend over the entire height of the neck.
- According to a particular embodiment, the tube head further comprises an insert which is arranged so as to rest against the shoulder, so as to form a barrier between the tube head and a product contained in the internal volume defined by the skirt. In other words, the insert is arranged on an inner face of said tube head, opposite said outer face which is provided with flaps.
- The invention also relates to a method for manufacturing a tube for a product having a liquid or pasty consistency, wherein
-
- a skirt forming a cylinder of revolution is positioned around a threader, said skirt having a proximal end and a distal end,
- the skirt is slid along said threader by means of movable stops provided with a plurality of cutting tools, so as to produce a plurality of notches from the proximal end of the skirt, thus defining a plurality of flaps at the proximal end of the skirt, and so as to fit the skirt around a punch;
- a die is positioned around said punch, the die forming a recess together with the punch which defines a shape of tube head, comprising a shoulder and a neck, said die folding the flaps of the skirt such that they are shaped to the die over all or part of the recess defining the shoulder;
- plastics material is injected into said recess so as to form the tube head.
- According to a particular embodiment, an insert is positioned on the punch prior to the injection of plastics material.
- Other features, aims and advantages of the invention will become clearer from the following description, which is given purely by way of illustrative and non-limiting example and should be read with reference to the accompanying drawings, in which:
-
FIGS. 1 and 2 show partial views of a tube according to one aspect of the invention; -
FIGS. 3 and 4 show two views of an embodiment of a skirt of such a tube; -
FIGS. 5 , 6, 7 and 8 show an example of a tool for producing such a tube, and an example of the method for producing such a tube. - In all the drawings, common elements are provided with identical reference numerals.
-
FIGS. 1 and 2 are partial views of a tube according to one aspect of the invention, comprising -
- a
tube head 1, - a
skirt 2 and - an
optional insert 3.
- a
- The
tube head 1 comprises aneck 11 which defines a longitudinal axis Z-Z and ashoulder 12 which extends substantially radially from theneck 11. Abase 13 of theneck 11 is thus defined, which corresponds substantially to the connection between theneck 11 which has a generally cylindrical shape of revolution about the axis Z-Z and theshoulder 12 which extends substantially radially with respect to the axis Z-Z from theneck 11. - The
neck 11 comprises a thread 14 over the outer periphery thereof which is adapted to allow a cap which comprises a complementary thread to be screwed onto theneck 11. - The
skirt 2 is connected to theshoulder 12 so as to extend from the periphery thereof and to form an internal volume of the tube which is adapted to receive a product having a liquid or pasty consistency. - The tube as shown further comprises an
insert 3 which is arranged so as to rest against theshoulder 12, against an inner surface of theshoulder 12, so as to form a barrier between the tube head and a product contained in the internal volume. Theinsert 3 as shown is solid, and thus forms an inner seal which blocks theneck 11. This may be an insert comprising a barrier layer, which is covered with one or more protective layers, in particular made of polymerised materials. The barrier layer may be made of metal, in particular of aluminium, or made of EVOH. - As shown in
FIG. 2 , theskirt 2 has aproximal end 21 which is folded onto an outer surface of theshoulder 12 and, more generally, onto an outer surface of thetube head 1. In order to allow such a fold to be made without producing ripples in the region of thisproximal end 21 of theskirt 2, said skirt has a plurality ofnotches 23 which thus define a plurality offlaps 24 which are folded onto theshoulder 12 of thetube head 1. - The
flaps 24 which are thus formed cover all or part of theshoulder 12, typically at least 50% of the surface of theshoulder 12. - According to a particular embodiment not shown, the
flaps 24 are dimensioned so as to extend as far as the base of theneck 12, and therefore cover all of theshoulder 12. In a variant, theflaps 24 can also extend over all or part of theneck 11. -
FIGS. 3 and 4 show two views of an embodiment of askirt 2 as presented above. - The
skirt 2 forms a cylinder of revolution, and has aproximal end 21 and adistal end 22. - The
proximal end 21 has a plurality ofnotches 23 as presented above, thesenotches 23 thus defining a plurality offlaps 24 therebetween which are formed in the material of theskirt 2. - In the embodiment shown, the
notches 23 are cuts which are made from theproximal end 21 of theskirt 2, substantially perpendicularly to saidproximal end 21, each of thenotches 23 advantageously having an identical length, and thenotches 23 are advantageously distributed regularly along theproximal end 21 of theskirt 2. Thenotches 23 typically extend in parallel with the axis Z-Z, which corresponds to an axis of revolution of theskirt 2. - The
flaps 24 which are thus formed are therefore similar or identical. -
FIG. 4 schematically shows the foldedflaps 24 in a position corresponding substantially to the configuration of the flaps shown inFIG. 2 . In this configuration, theflaps 24 form a non-zero angle with the remainder of theskirt 2. - It can be seen from this figure that the adjacent flaps cover one another in part owing to the reduction in diameter between the diameter of the cylinder of revolution of the skirt as shown in
FIG. 3 and the internal diameter of the reduced cross section which is defined once theflaps 24 are folded. - It is clear that in the absence of the
notches 23 made in theskirt 2, the fold in theproximal end 21 thereof would lead to ripples and therefore to an irregular surface, degrading the appearance of the attached tube head as well as the mechanical properties thereof due to the irregular shape of the skirt which causes uncontrolled injection of the material forming thetube head 1. - The length of the
notches 23 determines the dimensions of theflaps 24, and therefore theshoulder 12 can be covered;longer notches 23 allow a greater surface area of theshoulder 12 to be covered while preventing ripples in theskirt 12. By contrast, the lower the dimensions of thenotches 23, the lower the surface area of theshoulder 12 which can be covered by folding theskirt 2. - It is also clear that the number of
notches 23 also influences the possibility of folding theproximal end 21 of theskirt 2 without forming ripples; the higher the number ofnotches 23, the lower the dimensions of theflaps 24, and therefore the more possible it is to fold said flaps towards the inside of theskirt 2 as shown inFIG. 4 without forming ripples. - The
notches 23 may also be produced in several ways. They may be simple cuts without removing material as shown inFIG. 3 , or cuts involving removal of material, for example a portion having a triangular shape of which the base is formed by theproximal end 21 of theskirt 2, the shape of such cuts being configured depending on the dimensions of theskirt 2 and of thetube head 1, and of the covering by theskirt 2 which is sought. - By way of example, the following non-limiting variants are given:
-
- the diameter of the
skirt 2 may range between 19 and 50 mm, - for a
skirt 2 having a diameter of 25 mm, the number of notches may range between 12 and 32 notches, - the width of the notches in the region of the proximal end of the skirt typically ranges between 2 mm and 6 mm,
- the covering is typically between 0.2 mm and 1 mm.
- the diameter of the
-
FIGS. 5 , 6, 7 and 8 show an example of a tool for producing such a tube, and an example of the method for producing such a tube. -
FIG. 5 shows askirt 2 which is mounted on a tool element which is usually referred to as athreader 4. Thisthreader 4 has, for example, a cylindrical shape of revolution such that it is possible to fit theskirt 2 around it, and comprisesmovable stops 41 which can be moved along the length thereof, such that during the movement of said stops, they slide theskirt 2 along thethreader 4. Saidmovable stops 41 are further provided withcutting tools 42 which are distributed over the periphery of thethreader 41, such that during the movement of themovable stops 41 along thethreader 4, thecutting tools 42 will firstly come into contact with theskirt 2, and will then produce notches in theproximal end 21 thereof. Once said notches are made and the flaps are formed as described above, said notches abut the movable stops, which thus cause theskirt 2 to move along thethreader 4. -
FIG. 6 thus shows the position of themovable stops 41 once the notches are made in theproximal end 21 of theskirt 2; the movable stops push theskirt 2 so as to make it fit around apunch 5. -
FIGS. 7 and 8 show the position of adie 6 relative to thepunch 5, thedie 6 and thepunch 5 defining an internal volume therebetween which defines the shape of the tube head that is intended to be produced;FIG. 8 thus shows the shape of theshoulder 12 and theneck 11 of a tube head as defined above. - As shown in the drawings, the positioning of the
die 6 causes the folding of theproximal end 21 of theskirt 2, such that it is substantially shaped to the shape of thedie 6 which defines theshoulder 12 and, if necessary, theneck 11. - Plastics material is then injected to form the tube head in the internal volume which is defined by the
punch 5 and thedie 6. The plastics material thus injected will then become connected to theskirt 2, ensuring cohesion between theskirt 2 and thetube head 1. - In a variant, an
insert 3 is positioned on thepunch 5 before theskirt 2 is positioned or before thedie 6 is positioned, thus allowing thetube head 1 to become connected to theinsert 3 during the manufacturing thereof. - The present invention thus makes it possible to exploit the properties of the
skirt 2 in order to improve the mechanical properties of thetube head 1. Furthermore, in the case of atube head 1 comprising aninsert 3, the invention makes it possible to improve the properties of thetube head 1 by significantly reducing the permeability at the edge of theinsert 3.
